(3) Derate linearly 6.66 mW/o C above 25o C. (4) The OPB770T thru OPB773T series are terminated with 12 inches of 7 strand 26 AWG, UL1429 insulated wire on each terminal. A standard AMP No. 640442-5 connector has been attached to the lead wires to ease connection to wire harnesses. (5) Normal application would be with light source blocked, simulated by IF = 0 mA. (6) Tested at d = 0.080" from a 90% diffuse white test surface. (7) Tested at d = 0.080", 0.150" and 0.220" from a 90% diffuse white test surface. Reference: Eastman Kodak, Catalog #1257795. (8) Tested at d = 0.080", 0.150" and 0.220" from a 5% diffuse black test surface. (9) All parameters tested using pulse technique. For RoHS compliant devices add "Z" to the end of the part number: OPB770TZ Optek Technology, Inc. 1215 W.
